Nickel Release Test
Nickel Release Test
The nickel release rate is closely related to the corrosion resistance of an alloy. So improving the corrosion resistance would be beneficial to reduce the nickel release rate. The release rate depends on processing technologies and surface treatment methods. Ni release rate sequence (from big to little) is as follows:
- Annealing at the two-phase region with a rough surface
- Cold working with a rough surface
- Cold working with a polishing surface
- Quenching with a rough surface
- Quenching and low temperature tempering with a rough surface
Two characterization techniques which are anodic polarization curves and Scanning Electron Microscopy (SEM) are used.
